High Speed Central Drum Flexographic Printing for Bag Printer Machine

                          Six colors High-speed CI Flexo printing machine




Use: 
This High speed CI flexo printing machine is suitable for printing such   packing materials   as polyethylene, polyethylene plastic bag glass paper and roll paper etc. And it is a kind of ideal printing equipment for producing paper packing bag for food, supermarket handbag, vest bag and clothes bag, etc.
 


Main parameter:  


Sample:



Feeding material part:
1.Single unwinder system, pneumatic loader for unwind system 
2.Automatic stop machine when break the material; When machine stop, keep tension and avoid the material loose or line deflection.
3.Air shaft 
4.EPC (edge position control): With manually/automatically/ central return function, can adjust the rewind move left and right .
5.Automatic tension control system with magnetic brake(10KG).
6.Roller core diameter: 76mm 
7.Discharge maximum diameter: 1000mm

Printing sections: 
1.printing consists of: central drum, plate roller, ceramic anilox roller, chamber doctor blade.
2.plate roller circumference: 280-1000mm 
3.print material: resin plate or rubber plate 
4.Transmission: central drum with big gear drive the printing station. 
5.adjustment method: Motorized longitudinal registration and Motorized Transversal Registration.(Automatic printing after adjust by motor, when start machine, no need register color again, the printing pressure and register all keep the same.) 
6.Printing roller lifting system: Penumatic cylinder control roll backward and forward , when the machine stop the printing cylinder will backward , when the machine running will forward by penumatic cylinder automatic.

Electrical parts: 
1.Main Motor: 7.5kw 
2.heating and dry power 40kw .
3.Pull motor 1.5kw
4.Rewind motor :3.7KW
5.Ink motor and the color register motor 1.5 KW
6.The machine total consumption about 55 kw 
7.Speed using frequency converter control 

Rewinding Part:
1.Single rewinder system, pneumatic loader for unwind system 
2.Automatic tension control system with magnetic brake(10KG).
3.Air shaft.
4.Roller core diameter: 76mm 
5.Discharge maximum diameter: 1000mm

Central drum
1.The central drum adopt hollow with two layers structure, made from superior alloy
2.steel and precise dynamic balance treatment and surface electroplated treatment to make the frame surface without etching.
3.The central impressing drum adopts high precise imported double row roller
4.bearing for supporting, imported together with the central drum.
5.The central impressing drum has constant temperature system of 32ºC. With water cooling system(optional)
6.The central drum is driven by a big gear
7.A high precision encoder is installed at the axial head of the central drum which speed of plate cylinder and anilox roller is synchronous with the central drum

Chamber doctor blade and ink pump 
1.Equipped with doctor chamber for fast change.
2.It is made from Aluminum alloy and closed type to reduce solvent volatilization
3.and keep the ink in good viscosity and clean.
4.The blade and chamber sealing block are easy to change and clean.
5.There is forward and reverse directions doctor inside the chamber. The reverse
6.doctor is for sealing the chamber and the forward doctor is for scratching the ink.
7.The doctor blade is with even strength, easy to adjust.
8.ink supply adopt double diaphragm pump. Easy to suck the ink .
